Pick the approved compensation path, not a net-of-fee guess. Aggregator event pay is capped at $6/kWh in the order summary, but event counts are not modeled here, so the default aggregator figure is the $90/kW-year reservation only and is labeled as incomplete until dispatch rules are published.

|---|---|---|---|
| BGE residential BYOD — standalone storage or bidirectional EV | $300/kW-year based on nameplate capacity | VGIC summary of the approved MD PSC order. First season expected summer 2027. | VGIC — Maryland Approves New Vehicle-to-Grid Pilots (July 13, 2026) ↗ Last verified: Nov 12, 2026 |
| BGE residential storage + solar | $150/kW-year based on nameplate capacity | Lower direct-enrollment tier when storage is paired with solar. | VGIC — Maryland V2G pilots ↗ Last verified: Nov 12, 2026 |
| BGE aggregator participation | $90/kW-year reservation on pledged capacity, plus event pay up to $6/kWh | This calculator defaults to the $90 reservation only. Event pay is officially capped at $6/kWh but event counts are not published here, so they are omitted (estimate: $0). | VGIC — Maryland V2G pilots ↗ Last verified: Nov 12, 2026 |

The Fine-Print Catches: 4 Rules Utility Brochures Bury
No program payments until the 2027 summer season
VGIC’s July 13, 2026 article says implementation timing varies by utility and programs are anticipated for the 2027 summer season. Do not treat these annual figures as 2026 cash.
The aggregator rate is $90/kW-year plus event pay, not $255
A 15% haircut on the $300 direct tariff is not the approved aggregator structure. The approved reservation payment is $90/kW-year, with event payments up to $6/kWh.
These payments are incremental to the vehicle
A $3,000/year bidirectional-EV illustration on a 10 kW charger does not pay back the car. The $6,400 figure in the hardware list is a charger-cost estimate only.
Nameplate vs. actual export
The $300 and $150 residential figures are described as nameplate-based. Actual enrollment rules may still require the charger or battery to be available during events.

Worked Household Bill Math: Real-World Scenario
BGE residential customer — 10 kW bidirectional charger (program value, not vehicle payback)
1,250 kWh/month usage; 131 kWh EV plugged in at home by 3:30 p.m. on summer weekdays.
- Direct BYOD standalone / bidirectional EV path: 10 kW nameplate × $300/kW-year = $3,000/year in program payments, expected to start summer 2027 — $0 from this tariff in 2026.
- Aggregator path on the same 10 kW: 10 × $90 = $900/year reservation. Event pay of up to $6/kWh is not added because event counts are unpublished in our sources.
- Charger hardware around $6,400 is an estimate and excludes the vehicle. This page does not compute a payback period against the car.
- Confirm final tariffs and interconnection rules on the utility and PSC record before you buy equipment.
Frequently Asked Questions (BGE, Pepco, Delmarva Power & Potomac Edison)
Do Maryland DRIVE Act $300/kW-year V2G payouts pay out in 2026 or 2027?
Summer 2027 is the expected first dispatch season, according to VGIC’s July 13, 2026 summary of the Commission’s program order. Do not count on 2026 checks from this tariff.
Why does a bidirectional EV earn more per year than a single home battery?
kW-year tariffs measure average kW sustained across a multi-hour event. A single 13.5 kWh home battery is energy-limited to ~3.2–3.6 kW over 3 hours, whereas a 100+ kWh EV pack sustains the full inverter rating for the entire window.
Which Maryland utilities are covered by the DRIVE Act pilots?
Baltimore Gas and Electric (BGE), Pepco, Delmarva Power, and Potomac Edison are all mandated to participate toward the 185.7 MW statewide target.
Is the aggregator payment $255/kW-year after a 15% fee?
No. The approved aggregator structure in the VGIC order summary is a $90/kW-year reservation on pledged capacity plus event payments of up to $6/kWh, passed through the aggregator — not $300 minus 15%.
